Cyril Tovena	8716e24518	Allocate entries array with correct size while decoding WAL entries. (#3241) ... Small optimization I found while deployment the new version. We might want to have a pool of entries here. ``` ❯ benchcmp before.txt after.txt benchmark old ns/op new ns/op delta Benchmark_DecodeWAL-16 2350024 1591633 -32.27% benchmark old allocs new allocs delta Benchmark_DecodeWAL-16 20043 20005 -0.19% benchmark old bytes new bytes delta Benchmark_DecodeWAL-16 4946246 1763270 -64.35% ``` Signed-off-by: Cyril Tovena <cyril.tovena@gmail.com>	5 years ago

Cyril Tovena	0a81f70800	Improves checkpointerWriter memory usage (#3188) ... * Logs PushRequest data. This will allows to find information about received size and total entries per tenant. Example of a log from my dev testing: ``` level=debug ts=2021-01-15T11:16:21.735663076Z caller=http.go:67 org_id=3927 traceID=11c4774c6ec4bbf4 msg="push request parsed" path=/loki/api/v1/push content-type=application/x-protobuf body-size="11 kB" streams=5 entries=298 streamLabelsSize="1.9 kB" entriesSize="45 kB" totalSize="47 kB" ``` Of course this means we can use LogQL on this.
